All things dark and beautiful indeed: LA combo Isis are masters of sculpting the darkness, teasing out the weird shapes that lie just out of view. The music on Panoptician is blank and searching, stark chiaroscuro whorls of sound that pitch and roll over and over and over. "In Fiction" is marvelous monotony, a single series of riffs circling over and over and over until the bottom falls out and the whole song goes rushing suddenly, terrifyingly downward. "Wills Dissolve" is like June of 44 corrupted by evil, long strings of sound dripping icicle-like. It's these reveals — abrupt, noisy, volcanic — that make Panoptician so utterly terrifying. Like a ghost leaping from a closet door, Panoptician is full of sickening surprise.
